My take: If anyone ever posts anything that's blatantly false or a big fat lie and makes you get a gut-reaction of anger, they are trolling you. A troll's only goal is to make you feel bad and to express that to them. Never fall into a troll's trap, cuz it stinks in there (and makes you smell like a troll too for a while)! That's my opinion at any rate, after having inadvertently fallen into a troll's trap. (I probably smell somewhat like a troll now too -- yuck!)
